    mac80211: add TX fastpath · 17c18bf8
    Johannes Berg authored
    In order to speed up mac80211's TX path, add the "fast-xmit" cache
    that will cache the data frame 802.11 header and other data to be
    able to build the frame more quickly. This cache is rebuilt when
    external triggers imply changes, but a lot of the checks done per
    packet today are simplified away to the check for the cache.
    There's also a more detailed description in the code.
